DROIPHEAD CABNET FOB, SEWING AND OTHER MACHINES.

Application filed February 16, 1922. Serial No. 536,949.

To all w hom t may concern Be it known that l, HENRY W. Genuine, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Qhio, have invented certain new and usefulImprovements in Brophead Cabinets for Sewing and Other Machines; and ldo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to that class of drophead cabinet-s in weich themachinesupporting bed is raised and lowered by means of a swinging leafhinged to the top of the cabinet and operatively connected with thesupporting bed through means including a cable. in cabinets of thisclass, when the bed is raised to bring the supported machine to workingor operative position above the top of the cabinet, it is desirable thatthe bed should always be brought to a predetermined positionsubstantially flush with the top or table of the cabinet. To do this itis necessary that some provision be made to take up or control the slackin the connecting cable between the bed and the operating table leaf,and ,it has been the object of my present invention to provide a simpleand efficient means for controlling the slack in such cable. rlhisobject l attain by the novel means illustrated in the accompanyingdrawings forming part of this specification, in which- Figure l is afragmentary view of a sewing machine cabinet, partly in section, showinga machine supporting bed hinged to the cabinet table, a swinging leafhinged to one end of said table, a cable between said bed and leaf, anda device embodying my invention secured to the bed for coupling one endof the cable thereto and having` means for taking` up slack in thecable.

Fig. 2 is an enlarged side elevation, partly in section, of the cablecoupling and adjusting device detached from the machine* supporting bed.

Fig, 3 is an end view of the same, showing the lower end of the cableconnected therewith as in Fig. 2, and

Fig. 1i is a top plan viewfof the same.

Similar reference characters indicate like parts in the several figuresof the drawings.

My invention may be applied to any type of cabinet or stand having amachine-supporting bed which is adapted to be operated through theinstrumentality of a cable t0 lower the machine into the cabinet whennot in use and to raise the machine above the cabinet top or table whendesired for use, the invention, as heretofore indicated, being directedparticularly to means for taking up slack in the cable resulting fromundue stretching of the same, whereby the bed may be always brought tothe same predetermined position when raised.

ln the drawings, which show only so much of a sewing machine drop-headcabinet as is necessary to illustrate my invention, 2 indicates the topor table of the cabinet having an opening 3 for the passage of themachine in being raised and lowered to and from its operative or workingposition; 1l, the machine-supporting bed pivoted at one edge to thetable within its said opening 3, as at 5; 6, a part of the frame of asewing machine mounted on said bed; and 7, a swinging leaf hinged to thetable at 8 and being movable from a closed position over the opening inthe table when the machine is lowered, to an open position extendingbeyond one end of the cabinet when the machine is raised, this leafoperating through suitable connections, upon its opening and closingmovements, to raise and lower the bed and the machine supported thereon.rlhese several parts as thus far described are of substantially usualconstruction and operation.

The bed il, as here shown, has a cleat 9 at its under side whichprojects beyond the rear edge thereof to form a stop-shoulder l() forengagement with the under side of the table when the bed is brought to araised position, as shown by dotted lines in Fig. l.

In the present case, the operating connection between the leaf and bedcomprises a cable l1 having coupling eyes 12, 12, at its opposite ends,one of which is connected with the leaf by suitable fastening means,such as the screw 13, and the other of which is connected with the rearedge of the bed 4 through the medium of my improved coupling andadjusting device, the cable be tween its ends passing through a guideopening la in the cabinet, as shown in Fig. l.

My improved cable coupling and adjusting device comprises a bracket l5attached to theI under side of the bed 4 by suitable fastening means,such as the screws 16, and

having a depending arm 17 provided with an opening 18 in which a lever19 is loosely seated for pivotal connection with the bracket. This lever19 is here shown as formed at its rear end with a hook 20 for detachableconnection with the coupling eye 12 in the end of the cable 11, and atits opposite or front end as bearing against an adjustable support, hereshown in the form of a nut 21 having a screw-threaded connection with apin 22 depending from and rigidly attached to the bracket 15. Byscrewing the nut 21 upwardly on the pin 22 it will operate to raise theengaging end of the lever and cause the latter to rock on its bearing atthe upper end of the opening 1S in the bracket and thereby lower itsrear or hook end, which movement of the latter will act to shorten thecable between the leaf and bed whereby the latter may always be causedto be brought to a raised position with its stop-shoulder 10 in contactwith the under side of the table.

As a means Jfor holding the lever 19 in its operative connection withthe bracket 15, that is, in position in the opening 1S, and also withits front end bearing on the adjustable support 21, it is engaged at itsfront end by the pin 22 which extends loosely through an opening 28therein as shown.

The lever 19 is here shown as resting on the washer 21 adjacent to oneedge thereof, whereby it will have a tendency to cant said washer andcause it to bind against the threads of the pin 22, in this way actingto lock the washer in its adjusted position.

The cable coupling and adjusting device herein shown and described is ofcheap and "f simple construction, and has been found to be mosteiiicient for the purposes intended.

What I claim is:

1. In a dropehead cabinet, the combination with the table, a movableleaf, a vertically movable machine-supporting bed, and a cableoperatively connecting the leaf and bed whereby the opening and closingof the leaf will effect a raising and lowering of the bed, of a bracketattached to the bed having a depending arm provided with an openingtherein, a lever loosely seated in said opening and having a rearhookshaped end for detachable connection with the lower end of the cableand also having an opening at its front end, a threaded pin carried bythe bracket loosely engaging the lever through the said opening at itsfront end, and a nut threaded on said pin providing an adjustablesupport for the front end of the lever, for the purpose set forth.

2. ln a drop-head cabinet, the combination with the table, a movableleaf, a vertically movable machine-supporting bed, and a cableoperatively connecting the leaf and bed whereby `the opening and closingof the leaf will effect a raising and lowering of the bed, of a bracketattached to the bed having a depending arm provided with an openingtherein, a lever loosely seated and pivoting in said opening and havingits rear end in connection with the cable and its front end providedwith an opening, a
